@dredmorbius @cwebber @njoseph @aral constraining protocols isn't possible using only #copyright (and every #free / #libre license, #copyleft or not, from @fsf or not, is based on copyright law to some extent). Fortunately, for example, in AGPL-3.0-or-later, it has provisions to allow software #patents to be used by licensee only in that copy and adaptations, thus #ActivityPub can be secured from EEE with a patent?
